I have a problem creating a reverse DNS record.
First of all, I have created a new zone. IP was aaa.bbb.ccc.ddd and Domain was ccc.bbb.aaa.in-addr.arpa.
Second, I have edited the just created zone and I added a PTR record:ddd IN PTR domain.com, TTL 14400
After I saved it and go again to edit the zone, I can see that system added .ccc.bbb.aaa.in-addr.arpa. to the record.
Anyway, after 24 hours, I connected to the console using SSH and run this command: dig -x aaa.bbb.ccc.ddd
I saw this output:
; <<>> DiG 9.11.4-P2-RedHat-9.11.4-16.P2.el7_8.6 <<>> -x aaa.bbb.ccc.ddd

As you see, this value is shown for the PTR record: unknown.ord.scnet.net
and I cannot get rid of it.
What is wrong?
